OEX Starter Motor 12V 11 Tooth CW Denso DXS621

The OEX starter motor DXS621 is a new 12V unit for Denso applications, with 11 teeth, clockwise rotation and a 2kW power rating. It is listed as a dry clutch starter motor with a 2 hole starter mount type, so the mounting style and rotation need to line up with the original unit before purchase.

Key dimensions include a 112mm mount centres A measurement, 74mm flange diameter, 9.5mm mount hole diameter, 34mm pinion diameter and 20mm pinion at rest. Those measurements are the practical checks that matter when comparing against a removed starter, especially where similar-looking starters differ in flange size, hole spacing or pinion setup.

This is an OEX branded starter motor, sourced from ISO certified factories and backed by a 3 year passenger / 1 year commercial warranty. It is supplied as each, and the listed fitment information references a wide range of machinery and vehicle applications, including CASE, Ford, New Holland, Gehl, Perkins, Shibaura, Vermeer and Yanmar models.

Application and Buying Notes

When matching this starter motor, confirm the part number DXS621 first, then compare the mounting and drive details against the unit being replaced. The important checkpoints here are 12V, 11 teeth, clockwise rotation, 2kW output, 2 hole mount type, 112mm mount centres A and 74mm flange diameter.

The pinion measurements also matter. This unit is listed with a 34mm pinion diameter and 20mm pinion at rest, so it should only be considered where those dimensions align with the original starter arrangement. Even if a machine make appears in the fitment references, the physical starter can still vary between applications.

The fitment references include a broad spread of equipment, but they are still application guides rather than a substitute for checking the original part. For the safest match, compare the removed starter, the mounting pattern, the rotation direction and the drive tooth count before ordering. That is especially important on equipment where multiple starter options can be used across the same series.

As a new OEX starter motor, this unit is intended for buyers who want a fresh replacement rather than a remanufactured assembly. The listed warranty is 3 years for passenger use and 1 year for commercial use, so it is worth confirming the intended vehicle or equipment use when assessing the warranty term that applies.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number DXS621 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

OEX Starter Motor 12V 11Th CW Denso. Part number DXS621 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number DXS621, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ALLIGHT MS10K, ALLIGHT MS12K, ALLIGHT MS4.5K, ALLIGHT MS6K, CASE 21E, CASE 21E 2008. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Please confirm fitment using part number DXS621, the 12V electrical requirement, 11 tooth CW configuration, 2 hole mounting pattern and the listed dimensions before ordering.
